two annular sections, D D, which are counterparts of each other and arranged face to face, and of a shape on their perimeters corresponding with the exterior form of the required felly in its transverse section. These annular sections D D are separated from each other at their hubs by a plate or disk, b, the thickness of which may be varied, according to the required width of the felly.

E is an upper frame, mounted on the main frame A, and arranged to extend above the former-wheel D D, on the back or one side of it. This frame E carries, by means of brackets c 0, arranged at suitable distances apart, guides or guide-rollers d 01, arranged to bear on the outer sides or faces of the annular former wheel-sections D D in their upper course of travel. The outer ones, 01, of these rollers may be adjustable in slots 0 of the brackets, to provide for varying the distance apart of the annular sections D D, to suit dif ferent widthsof felly,accordinglyas a thickei or thinner disk, I), is introduced between till annular sectionsDD, or as wear or other exi gencies may require.

DAVIS, of Elmira, in the county of Uhemung and State of New York, have invented certain new and useful Improvements in Machines for Forming'Metal Fellies; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had part of this specification.

This invention more particularly relates to the manufacture of U or trough shaped steel or metal fellies for the wheels of wagons and other vehicles.

The invention consists in a revolving wheelformer composed of two annular sections, arranged face to face with each other, but separated at their center by a disk or packing, in

ers on the upper or one side of the axis of said former, and arranged to keep the two annular sections thereof in proper forming relation with each other on said side of the axis, while such annular former-sections are free to spring apart on the other side, to facilitate the delivery of the felly after the same has been formed by its passage between and around the confined forming portions of the annular sections of the revolving wheel-former, and under any number of free forming-rollers entering within the latter.

The invention also consists in certain combinations of adjustable forming-rollers and adjustable guide-rollers with the rotating annular wheel sections which constitute the wheel-former, whereby the felly is more perfectly formed, and provision is made for adjusting the machine to make different diameters, thicknesses and widths of fellies. of felly, or as wear of the working parts Ill.
